Flight of Stairs ABSTRACT The invention concerns a flight of stairs with a multiple of steps - where each step is firmly connected at least at one lateral end with the subsequent step by two vertical members, and where the bottom and top steps (22, 12) are resting on an intermediate floor (26, 24), a landing beam or a similar member, and where at least one lateral end of each step (12 to 22) is arranged within a square support - consisting of two horizontal and two vertical members (40, 42; 44, 46) which, together, form a stair stringer - in such a manner that each step is supported by its assigned horizontal member beneath it, and that each horizontal member (40, 42) is extended beyond a vertical member (44, 46), so that the extension (32) of the upper horizontal member (40) forms the lower horizontal member of the next step (12) above, while the extension (48) of the lower horizontal member (42) forms the upper horizontal member of the next step (16) beneath it, and where - at least on one side - a vertical member can be replaced by a spacer (206, 208, 306) or by the actual step (124, 128, 130) which, in this instance, must - at least on that side - be of the same thickness as a step height.
